This Zapier template will send you an email alert when someone leaves a form or a checkout process prior to completing it. Then you can reach out to that person to remind them to continue the process or offer help.
You can customize this template to send an automated email to the contact directly. But we recommend you start out with alerts first to make sure everything works as you expect it to.
